as citizen of the United st-ates, residing at- 319-Clifton avenue,.Newark, count --of Essex, and- State of. New. Jersey; have inventedcertain fnew and useful Improvements .in Adjustable Sleeves for Journal- Bearings, fully: described and represented in the folj lowingspecification and the accompanying l 5 provided with any member, asa.bevel-gear pinion, which requires adjustn'ient longitudinallyto-operate in a proper manner. To adjust the shaftlongitudinally, anabutment or thrust-bearing connected with the roller bearing isrequired',-.against which the'thrust -ot the shaftmay be sustained whenpushed forward bythc operation of the sleeve, and such abutment may bereadily formed by an anti-friction thrust-collar fitted to afshouldernear one end of the roller be'arirl f'.

and arranged to contact with the end of the The rotation of such nutserves to push the sleeve forward as may he required, and the nut whenthus adjusted ma be secured by the set-screw 2. Such bearings arecommonly lubricated, and the end of the adjusting nut- 2 furnishes astationary shoulder against which the end of the sleeve revolves withproper lubrication, and thus operates like any collar upon a shaft. tore- It is common to divide the gear-case and connected parts of theconstruction shown in the drawing. to give access tothe interior so thatthe collar 1 or the nut. .2 mavbeturned to adjust the pinion 1'whenrequired. The parts 1 and .2 hoth consist. of threaded collarsarranged to adjust the sleeve when required.

.From the above description it will he seen that. the sleeve is utilizedto perform two functions, first, protecting the shaft from wear at thepointin contact with the rolls h, and second, transmitting any endstrain upon the shaft to a, suitable abutment which may or may not beformed of a rotating thrust-ring. I

In the drawing, a screw-collar is shown to adjust the sleevelongitudinally, but it is immaterial what mezins be employed for thatpurpose.

Having thus set forth the nature of the invention whatis claimed hereinis:

1. The combination, with a suitable hearing, ofa shaft fitted to revolvein the'said bearing and having a wearing-sleeve fitted to the shaft and'revolving therewith in'the bearing, means for holding the sleeve fromrotation and end movement upon the shaft, an abutment adjacent to thehearing at one end of the sleeve, and means applied to the sleeve and tothe abutment for adjusting the.

shaft. longitudinally.

2. The combination, with a suitable bear-- mg, of a shaft fitted torevolve in the said bearing and having a driving-gear as thebevel-pinion 2', upon the shaft requiring longitudinal adjustment, :1wearing-sleeve fitted to'the shaft and revolving therewith in thebearing, means for holding the sleeve from rotation and end movement uon the shaft, an abutment adjacent to the caring at the end opposite tothe said driving-gear, and means applied to the sleeve and the abutmentfor adjusting the shaft and its attached part longitudinally.

3. In a roller bearing, the combination, 4

with the shaft, the casing and the anti-friction rolls, of awearing-sleeve fitted to the shaft and provided with a screw-thread atone end, means for preventing end movementoflthe sleeve upon the shaft,an abutment adjacent totl1e,- rol1erbearing, and a nut fitted adjustablyto the thread upon the sleeve and contacting with the abutment foradjusting the shaft longitudinally.

4. In a roller bearing, the combination, with the shaft, the casingandthe anti-friction rolls, of a wearing-sleeve fitted to the shaft andprovided with a screw-thread at one end, means for preventing endmovement of the sleeve upon the, shaft, an abut-- ment. at one end ofthe roller bearing provided with an anti-friction thrust-collar, and anut fitted to the thread upon the sleeve and eontactingwith thethrust-collar to adjust the shaft longitudinally..

5. In roller bearing, the. combination,

-with a. casing and anti-friction rolls, of a shaft, fitted therein, agear pinion fitted movably upon the end of the shaft, a feather forholding the inion adjustably upon the shaft, a wearing-sleeve fitted tothe ,shaft contiguous to the saidmember and engaging at one end with thefeather projected from the said member, andprovidcd at the opposite endwith a screw-thread, an abutment at such end of the roller bearingprovided with an anti-friction thrust-collar, a nut fitted to the threadupon the sleeve and contacting with thethrust-collar, and means forlocking the nut upon the sleeve when the shaft is suitably ad usted.
